Fort Sill is located approximately 90 miles southwest of Oklahoma City and approximately 50 miles north of Wichita Falls, Texas on Interstate 44. The City of Lawton, Oklahoma, borders Fort Sill to the south. The installation covers approximately 94,000 acres characterized by mountains, rolling hills, and prairie in Comanche County, Oklahoma.
The Fort Sill JLUS Study Area was designed to encompass all operational areas of the installation, as well as all land in the vicinity that may impact current or future military operations or be impacted by those operations. The proposed Study Area of the Fort Sill Regional JLUS is the initial area of investigation for the collection of data and information. The final Study Area will be refined based on information collected and input from the public and the JLUS communities.
